Intshayelelo kwiimveliso ze-silicon emnyama kunye nokusetyenziswa kwazo kwi-sandblasting
I-silicon emnyamasisixhobo sesilicon esisebenzayo esinesakhiwo esikhethekileyo somphezulu, esibizwa ngokuba nobuchule baso bokufunxa ukukhanya obunamandla kakhulu kunye nemo yendalo yomphezulu we-micro-nano eyahlukileyo. Kwiminyaka yakutshanje, ngokuphuculwa kokuchaneka konyango lomphezulu kunye neemfuno zokusebenza kwezinto kwimveliso ephezulu, i-silicon emnyama isetyenziswa kakhulu kwi-photovoltaics, i-optoelectronics, ii-semiconductors, i-optical component manufacturing kunye nezinye iindawo ezineempawu zayo zomzimba nezekhemikhali ezibalaseleyo. Kwangaxeshanye, i-silicon emnyama iye yangena kancinci kancinci kushishino lwe-surface sandblasting kwaye iye yaba luhlobo olutsha lwezinto ze-sandblasting ezisebenza kakuhle kakhulu.
Ⅰ. Iimpawu ezisisiseko zesilicon emnyama
I-silicon emnyama yenziwa ngokunyanga umphezulu we-silicon ngokusebenzisa uthotho lwetekhnoloji yokulungiselela ulwakhiwo lwe-micro-nano (ezifana nokugrumba kwe-ion esebenzayo, ukugrumba kwekhemikhali okuncediswa yisinyithi, ukugrumba okubangelwa yi-laser, njl.njl.). Umphezulu wayo ubonisa ikhowuni exineneyo okanye isakhiwo sekholamu, esinokunciphisa kakhulu ukugrumba kokukhanya. Ukugrumba kwibhendi ebonakalayo ukuya kwe-infrared kunokuba ngaphantsi kwe-1%, ngoko ke imbonakalo yayo imnyama mnyama.
I-silicon emnyama ayinazo nje kuphela iimpawu ezintle zokukhanya, kodwa ikwanazo neenzuzo zokuqina okuphezulu, ubumsulwa obuphezulu, ukumelana nokuguguleka, kunye nokumelana nokugqwala. Ulwakhiwo lwayo lwamasuntswana luqinile kwaye lufanelekile kwiindlela ezininzi phantsi kweemeko zempembelelo ekhawulezayo. Isebenza ngcono kwisanti kune-abrasives zendabuko ezifana ne-white corundum, i-brown corundum, isanti ye-quartz, njl.
Ⅱ. Iingenelo zesilicon emnyama ekuqhumiseni isanti
Ukuqhumisa isanti yindlela yokulungisa umphezulu esebenzisa ukuhamba kwesanti ngesantya esiphezulu ukuze kuchaphazele umphezulu ukuze kucocwe, kususwe umaleko we-oxide, kugrunjwe okanye kuhonjiswe. Njenge-abrasive esebenza kakhulu, i-silicon emnyama ineengenelo ezicacileyo kwicandelo lokuqhumisa isanti:
1. Isiphumo somphezulu esihle nesifanayo
Ulwakhiwo lwejometri yamasuntswana e-silicon amnyama luqhelekile kwaye imo izinzile. Emva kokutshiza, inokwenza isiphumo esifanayo nesihambelanayo se-matte kumphezulu wesixhobo somsebenzi. Esi siphumo sonyango sifanelekile ngakumbi kwiimveliso ezifana neglasi ye-optical, indlu yelensi, iindawo zesakhiwo se-aluminium alloy, njl.njl. ezineemfuno eziphezulu kakhulu zokuqina komphezulu kunye nembonakalo.
2. Ubulukhuni obuphezulu kunye nokumelana nempembelelo
Ubunzima be-silicon emnyama ye-Mohs bufikelela kwi-8.5 okanye ngaphezulu, izinga lokuqhekeka ngexesha lokuqhumisa isanti liphantsi, kwaye ubomi benkonzo bude. Xa kuthelekiswa nesanti ye-quartz eqhelekileyo okanye iiglasi, ukuqhumisa isanti ye-silicon emnyama kusebenza kakuhle kwaye kunamandla okubetha ngamandla, kwaye kunokugqiba ukucoca okunzulu kunye nokurhawuzelela ngexesha elifutshane.
3. Ubunyulu obuphezulu kunye nokukhuselwa kwendalo
Ubumsulwa be-silicon emnyama buhlala bungaphezulu kwe-99%, kwaye ayinazo izinto ezingcolisayo ezinobungozi ezifana ne-silicon ekhululekileyo okanye iintsimbi ezinzima. Inothuli oluphantsi kwindawo yokusebenzela yokuqhumisa isanti kwaye ifanelekile ngakumbi ukusetyenziswa kumashishini acocekileyo kakhulu afana nezixhobo ze-elektroniki, izixhobo zonyango, kunye nokupakishwa kwe-semiconductor. Kwangaxeshanye, imo yayo yamasuntswana izinzile, ukuveliswa kothuli kuncinci, kwaye ikhuselekile kwimpilo yabaqhubi.
4. Ingasetyenziswa kwakhona kwaye ilawuleka ngeendleko
Ngenxa yobunzima bayo obuphezulu kunye nokuzinza kwesakhiwo, i-silicon emnyama isenokugcina isiphumo esihle sokutshiza emva kwemijikelo emininzi, nto leyo enciphisa kakhulu ukulahleka kwezinto. Kwizixhobo ezinkulu zokuqhumisa isanti ngokuzenzekelayo, i-silicon emnyama ibonisa uqoqosho olungcono.
Ⅲ. Iindawo eziqhelekileyo zokusetyenziswa
Iibrasives zesanti zesilicon emnyama zisetyenziswa kakhulu kwezi ndawo zilandelayo:
Unyango oluchanekileyo lwe-hardware surface matte: njengesakhelo esiphakathi sefowuni ephathwayo, igobolondo lencwadi yamanqaku, igobolondo lewotshi ekrelekrele kunye nezinye iimveliso ze-aluminium alloy;
Unyango lwe-optical glass frosting: olusetyenziselwa ilensi, isihluzi, i-optical window matte kunye nokuhombisa;
Iindawo zeenqwelo-moya nezomkhosi: susa umaleko we-oxide ngaphandle kokutshintsha ubungakanani ukuze kuphuculwe ukunamathela kwengubo;
